5 / 171 page  5 AT75C DSP Subsystem 1368C–INTAP–08/02 Bus Architecture Data Buses Data is transferred via the X-data bus (XDB) and the program data bus (PDB), 16-bit bi- directional buses, and the Y-data bus (YDB), a 16-bit unidirectional bus. The XDB is the main data bus, where most of the data transfers occur. Data transfer between the Y- data memory (Y-RAM) and the multiplier (Y-register) occurs over the YDB when a multi- ply instruction uses two data memory locations simultaneously. Instruction word fetches take place in parallel over PDB. The bus structure supports the following movements: • Register to register • Register to memory • Memory to register • Program to data • Program to register • Data to program The bus structure can transfer up to two 16-bit words within one cycle. Address Buses Addresses are specified for the on-core X- and Y-RAM on the 16-bit unidirectional X- address bus (XAB) and the 11-bit unidirectional Y-address bus (YAB). Program memory addresses are specified on the 16-bit unidirectional program address bus (PAB). |
